I have my free two year upgrade, i like both phones a lot but which is better. I've had experience with the htc one x before and i recently saw the atrix and liked it a lot but i dont want to get a bad phone. which is better?
The HTC One X is far better than the Atrix. It has a far better screen, camera, processor, storage etc.
Nothing is better on the Atrix and the Atrix is older.
The One X is also better than the Atrix 2 and the Atrix HD
